, effectively the same as calling #==
, but typically overridden by descendants to provide meaningful semantics in case
statements.

Exclusive Or—Returns true
if obj is nil
or false
, false
otherwise.
static VALUE true_xor(VALUE obj, VALUE obj2) { return RTEST(obj2)?Qfalse:Qtrue; }

Or—Returns true
. As obj is an argument to a method call, it is always evaluated; there is no short-circuit evaluation in this case.
true | puts("or") true || puts("logical or")
produces:
